Editing Merges

For panoramic:

• edit pics BEFORE merging them if colors are varied from one to the next
• remember to try different types of merges (cylindrical, perspective etc)
• once merged flatten the image (layer>flatten) and edit as you see fit

For action sequences:

• each layer should line up (you can move them in PS if the camera moved)
• use your history brush if your selection was not perfect
